Preliminary Data Sheet
5 Port 10/100 Ethernet Integrated Switch
Features
General Description
IP175A PCB compatible (pins compatible)
IP175B integrates a 6-port switch controller,
Built in 6 MAC and 5 PHY
SSRAM, and 5 10/100 Ethernet transceivers.
Each port can be configured to be 10Base-T, Each of the transceivers complies with the
100Base-TX
IEEE802.3, IEEE802.3u, and IEEE802.3x
2k MAC address
specifications. The DSP approach is utilized for
Support auto-polarity for 10Mbps
designing transceivers with 0.18um technology;
Filter/ forward reserved address option
they have high noise immunity and robust
Broadcast storm protection
performance.
Auto MDI-MDIX
Support three MII/RMII ports
IP175B operates in store and forward mode. It
Support SMI with MDC up to 12.5 Mhz
supports flow control, auto MDI/MDI-X, CoS, port
Support tagging & un-tagging
base VLAN, bandwidth control, DiffServ, SMART
Support Port base VLAN & tag VLAN
MAC and LED functions, etc. Each port can be
Support CoS
configured to auto-negotiation or forced
Support port security option
10M/100M, full/half duplexmode. Using an
Support SMART MAC function
EEPROM or pull up/down resistors on specified
Support spanning tree protocol
pins can configure the desired options.
Max packet length 1552/ 1536 bytes
Support 8-level bandwidth control

port and one HOME/PNA or Access point. The
Low power consumption
external MAC can monitor or configure IP175B by
0.18um, 128-pin PQFP
accessing MII registers through SMI0.
MII/RMII port also can be configured to be MAC
mode. It is used to interface an external PHY to
work as a 5+1 switch. Through SMI1 IP175B can
monitor and configure external PHY.
